Objective-C Ruby

An Objective-C class (EmbeddedRuby for now) providing access to the Ruby interpreter. It relies on the Ruby and Foundation frameworks.

Currently works at a basic level with ruby 1.8.7 - can load a file, fork ruby, and give access to ruby's stdin/out/err. Untested with ruby 1.9.

Basic Example

	#import "EmbeddedRuby.h"

	EmbeddedRuby *ruby = [[EmbeddedRuby alloc] init];
	[ruby setFileName:@"reverse_stdin.rb"]; // pretend this exists, reads stdin, reverses & prints it to stdout

	EmbeddedRubyIO *io = [ruby forkRuby];
	NSFilehandle *stdin = [io rubyStandardInput];
	NSData *input = [@"This string should be reversed." dataUsingEncoding:NSASCIIStringEncoding];
	[stdin writeData:input];
	[stdin closeFile];

	NSFilehandle *stdout = [io rubyStandardOutput];
	NSString *output = [[NSString alloc] initWithData:[stdout readDataToEndOfFile] encoding:NSASCIIStringEncoding];
	[io close]; // closes stdin/out/err

	NSLog(@"%@", output);

Output:
